To all whom it may concern:

Be itknown'that I, CHARLESDE-MINICO, a citizen of the United States,residing at Portsmouth, in the county of Scioto and State of Ohio, haveinvented certain new and usefullmprovements in Sole-Leveling Machines;and I do hereby declare the following to be a full, clear, and exactdescrip- I tion of the invention, such as will enable others skilled inthe art to which'itappertains to make and use the same. i

The present invention relatesto sole' leveling machines and moreparticularly tomachines having a cooperating sole leveling roll and shoesupporting jack which are relatively movable in a longitudinaldirection. One object of the present invention is to prevent theleveling operation from bending the outstanding margin of the sole intoclose proximity to the upper and to maintain a substantially uniformthickness of sole edge. l/Vith this object in View a'feature'of theinvention consists in the-combination of a leveling roll, a shoesupporting jack, actuating mechanism for the roll and jack, and a soleedge support projecting beneath the outstanding margin of the sole tosupport the sole during the operation of the leveling roll.

further object of the invention is to provide an improved form of soleedge supportwhich 'is-particularly adapted to ma- 'le'veling machineembodying the several feachines of this "type and may be convenientlyadjusted to conform with di'fi'erent'styles of shoes.

and arrangements of parts hereinafter described and claimed, theadvantages of which will be obvious to thoseskilled in the art from thefollowing description.

In the accompanying drawings illustrating the'preferred form of theinvention; Figure 1 represents a side elevation of a titres of thevinvention; Fig. 2 is a detail illustrating upon an enlarged scale aside elevation of the sole edge support mounted upon the toe post of theshoe supportlng jack; Fig. 3 is adet-ail showing a plan view of the soleedge support in operatlve relation to a shoe; Fig.4: is a detail showinga cross sectionof the sole edge support taken bending of the sole margininto close proX- imity to the lasted upper and to maintain asubstantially uniform thickness of sole edge. To'this end the presentinvention contemplates the provision of means for positively supportingthe outstanding margin of the sole in a predetermined position dur ingthe leveling operation.

The present invention is shown in connection with a leveling machine ofa wellknown form having a shoe. supporting jack indicated generally at 1and journaled upon a rock shaft 2 supported in the front por-.

tion of the machine frame. The rock shaft 2 is actuated by suitablemechanism consisting of a cam 3 mounted upon a cam shaft 4,

and operative connections between the cam 1 and rock shaftto impart thepropermove- 'ments to the jack. The leveling roll is indicated at 6andis mounted to vibrate in a roll carrier 7 Secured to a sleeverotatably supported in a roll carrying bed pivotally mounted at 9 in theupper rear portion of the machine frame 10. The inclination of the rollrelative to the jack is varled automatically during the operation of themachine by actuating mechanism connected with the roll carrier 7. Theabove described mechanism specifically forms no part of the disclosed inthe application of Baxter, Ser. No. 750,326, filed February 24, 1913,and in consequence has been only briefly described herein.

The shoe supporting jack shown in the present invention consists of abed 15 having a toe post 16 formed integrally therewith, and a heel post17 slidingly supported 7 thereon. The heel post carries the usual lastpin and actuating mechanism and is adjustable toward and from the toepost to adjust the jack for varying sizes of shoes in a man- 8 which is7 present invention and is fully and groove connections erated throughan ner well-known to those skilled in the art. In order to support theoutstanding margin of the sole during theoperation of the machine a soleedge support is Conveniently arranged to project beneath the margin ofthe sole of a shoe supported upon the jack,

In the illustrated embodiment of the invention this sole edge support ismounted upon the toe post and'niay'b conveniently ad-' justed forvarying styles of soles. The toe post 16 carries a toe rest 18 which isadj ustably connected with the toe post by a sliding wedge 20 whichmoves in a slotted head 21 supporting and forming a part of the toerest. The wedge 20 is conveniently opadjusting screw '22 and hand wheel23. WVith this construction, upon a rotation of the hand wheel a bodilyvertical adjustment of the toe rest 18 rela tive to the toe post 16 issecured. In order to position the'sole edge support in a predeterminedrelation to the toe rest the support is conveniently'mounted upon themovable head 21. As shown clearly in the drawings, the sole edge supportembraces the forepart of the shoe adjacent to the toe and is providedwith a continuous engaging face projecting entirely about the toe andadjustable to conform to varying shapes of shoes. The sole edge supportis carried by a pair of brackets 25 and 26 respectively secured toopposite sides of the head 21. The'two brackets may be adjusted withrelation to one another and to the head'21 through the provision ofbolts 27 passing through elongated slots 28 formed in the brackets andthreadedly engaging in the head 21. The sole edge support propercomprises a pair of members 30 and 31 pivoted together at 32 upon an arm33 which is secured to the upper portion of the bracket 25. The arm 33may be adjusted in two directions relative to the bracket 25 through theprovision of a block 34: interposed between the'arm and bracket andhaving coiiperating tongue with the arm and bracket respectivelyextending at right angles to one another. The arm 33 is'secured inadjusted position relative to the bracket by a bolt 35 threadedlyengaging with the bracket and passing through elongated slots formed inthe arm 33 and block 34:. The members 30 and 31-are also supportedmidway between their ends by standards 36 and 37 which are slidinglysupported upon an inclined table 39 formed upon the upper portion of thebracket 26. The standards 36 and 37 are moved toward and from oneanother and are retained in adjusted position by an adjusting screw 40journaled in a bearing 41 secured upon the table 39 and havingoppositely threaded portions 42 and 43. The adjusting screw is retainedagainst longitudinal movement in the hearing by oppositely disposedcollars 'cific construction and and 45, and is conveniently rotated by aknurled thumb nut L6. \Vith this construction arotation oftheadjiist'ing 'serew' moves the standard'towar'd amrrrem one another,locking the members 3O and elabom: the pivot pin 32. Each of the members30 and 31 is conveniently connected with its corresponding standard by asleeve 17 which receives tlie reduced end of the standardand is securedby va tastening 48 to its respective member. With this construction aswivel connection is provided between each standard and the ooper ingmember, Permit g an angular mov ment of he memberr l tive to th t ndardwhe h members ar j t d oward d from ne h r- Th v bearing {11 isconveniently secured to the table, 39,. by a dependi g lug 5. ormed W9the bearing ancl projeotingthrough an elongated slot formed in thetable, the bearing being r d n P a 1 1 0.1 he ta le by a, n 51 h eaded ymoun ed, 91 the o er en of the lug 50. It will be noted that the inclination of the table 39 conforms substanti lly it th nclin ti n o thton part of the sole when supported upon the jack, and thus an adjustjet of the sole edge support in the direction of the length of the shoedoes not cause a displacement of the sole edge support vertically withrelatjion to that portion of the sole with which it n ge Fur erm re, itwi l b sat d that owing to the provision of the various adjustmentssubstantially a universal adj e t of h $0 edge airport w th r tion t theshoe may be obtaine n M to cause the sole edge support to exert asubs ny uniform pressure t ndi g to resis the thr t of t e leveli re l' t 'rrthe marring or' disfiguring of portion of the shoe with whichthe supportengages the two members are, prfiivided with acon tin a in 2 SPPPQHQ 3th 'ii mbe n ext n g b ut the tq enar't of the Sh o rport he Outst ndinmagm- Q't the so e.
